Question

I’m using Facebook JS SDK to develop a Facebook Page Tab application. There is a button in landing page. When clicked, user will be asked to install the App if they haven’t done so.

The codes are as follow:

<script type="text/javascript"> 
function installApp() {
    FB.login(function(response) {
        if (response.authResponse) {
            var accessToken = response.authResponse.accessToken;
        }
        if (response.status === 'connected') {
            window.location = 'share.php';
        } else {
            alert('Please install app first');
        }
    }, {scope:'friends_likes,email'});
}
</script> 

By default FB.Login will result in a popup box asking for permission. Is there any alternative way to AVOID the popup box? I have seen other Facebook apps successfully achieve this, but I have no idea how they did it.

Answer 1

Have you went through the Authentication documentation?

It pretty much cover all of the options that are available to you. i.e.:

1. Client-Side Authentication
2. Server-Side Authentication
3. Authentication within a Page Tab

You can probably use any of those approaches, but the 3rd probably will fit best.
